Osteological features associated with ankle hyperdorsiflexion

The habitual adoption of certain gestures and postural habits can result in a variety of non‐metric traits, including supernumerary facets that are both articular and non‐articular. The squatting facet is a classical example of the former, and generally presents as a lateral articular facet on the neck of the talus that articulates with a facet on the anterior border of the distal tibia. These facets arise owing to the adoption of the squatting position and the hyperdorsiflexed position of the ankle joint, bringing the talus and tibia into immediate approximation. This study reports on the difference between the classical squatting facet and a non‐articular facet, which can also present on the neck of the talus but occurs, probably, as a result of soft tissue pressure, rather than bony articulation. It is suggested that whilst the function of the two facets may be similar, their aetiology is likely to be very different. Copyright © 2001 John Wiley & Sons, Ltd.     

A foot deformity from a Romano‐British cemetery at Gloucester,England, and the current evidence for talipes in palaeopathology

A male skeleton from the Romano‐British site at Kingsholm, Gloucester, is described with abnormalities in the humerus, femur, tibia, fibula and foot. Computed tomography of the femora to enable cross‐sectional analysis suggested altered normal gait to compensate for the deformity. Differential diagnoses are considered and a diagnosis of clubfoot deformity is suggested. Palaeopathological evidence for clubfoot is rare in the literature but the cases reported to date are reviewed. Copyright © 2004 John Wiley & Sons, Ltd.     

Are legendary hominoids worth looking for? Views from ethnobiology and palaeoanthropology (Respond to this article at http://www.therai.org.uk/at/debate)

It has been suggested that the newly discovered hominin species Homo floresiensis may have survived on the Indonesian island of Flores so recently as to inform local images of small‐bodied hominoids. Taking an ethnobiological approach, the article discusses how this matter could be resolved empirically, and concludes that this will ultimately require physical evidence chronologically overlapping substantially with modern human populations. Further discussed are recent investigations affirming the resemblance of putative hominoids and what is known of Homo floresiensis, and a new initiative to excavate a Florenese site identified ethnographically as a mass hominoid burial. Whatever the outcome of these investigations, the case presents a challenge to sociocultural anthropologists inclined to interpret images of creatures undocumented by scientific zoology as purely social or cultural constructs.     

Cribra orbitalia: a non‐human primate perspective

Cribra orbitalia, a porous lesion involving the orbital roofs, is one of the most‐studied skeletal pathologies in bioarchaeology, and yet uncertainty still exists regarding its aetiology and significance. In contrast to the hundreds of reports of cribra orbitalia in human skeletal remains, little is known of this condition in non‐human primates. Previously, cribra orbitalia has only been reported in catarrhines, with just two cases in cercopithecoids. To provide a broader, phylogenetic perspective on cribra orbitalia, a sample of primate skeletal material was examined to evaluate the occurrence of this condition. The taxonomically diverse sample consists of 380 non‐hominoid (non‐ape) modern primates from both wild and captive populations. Cribra orbitalia is present in 16 individuals, including cercopithecines, colobines, platyrrhines and a prosimian, substantially expanding the known taxonomic range of this condition. Modern primates—with their varied habitats, diets, levels of parasitism, etc.—provide a set of natural experiments regarding conditions and physiologies which may influence the aetiology and impact of cribra orbitalia. More generally, it is suggested here that studies of non‐human primate skeletal pathologies have the potential for providing significant insight on human paleopathologies.

Morphological changes in the shape of the non‐pathological bony knee joint with age: a morphometric analysis of the distal femur and proximal tibia in three populations of known age at death

This study examines possible morphological variation in the knee joint of Homo sapiens with increasing age in ostensively healthy and non‐pathological distal femora and proximal tibiae. Throughout the lifetime of each individual, the hard tissue of the knee undergoes considerable remodelling as a response to biomechanical stresses, changes in bone microarchitecture and reduction of bone mineral content as a concomitant of ageing. The knee is also subject to greater levels of degenerative joint disease than any other joint. If death occurs whilst such diseases are in the earliest stages, initial bone changes may not be visually obvious in museum specimens. If such specimens are used for comparative analyses, it is hypothesised that changes might render it problematic if all ages are conglomerated into discrete samples. This study therefore investigates the degree to which the distal femur and proximal tibia change shape during ageing and, if changes are present, whether they are expressed similarly in males and females. It also examines whether changes are of greater magnitude than those morphological differences which might exist between populations. In an example population of African‐Americans, results indicate that there is a statistically significant difference in shape between age groups and those differences become progressively greater between the youngest and oldest adults. Results also show that although morphological variation caused by ageing is apparent, those shape differences attributable to sexual dimorphism are more powerful. When two additional populations are analysed jointly with the African‐Americans (Caucasian Americans and the European Spitalfields sample), results indicate that inter‐population shape differences are considerably greater than differences caused by increasing age. Results imply that it is justifiable to combine specimens of all ages into discrete samples for comparative purposes. Copyright © 2007 John Wiley & Sons, Ltd.     

New evidence for the antiquity of leprosy in early Britain

Examination of skeletons excavated in Dorset has probably produced the earliest example of leprosy known in northern Europe. The site, Poundbury Camp, Dorchester, was excavated under the direction of C. J. S. Green for the Dorchester Excavation Committee from 1966 to 1973. It is a Romano-British cemetery, apparently Christian, and the leprous bones are dated by their archaeological context to the middle of the fourth century AD.The specimen consists of the distal portions of right and left tibiae and fibulae, and the right and left feet. The right intermediate cuneiform is missing, but this may be a post-mortem loss. All parts of the skeleton above the mid-shaft of the tibiae and fibulae have been lost due to modern disturbance. It is therefore impossible to estimate the sex of the individual or its age, but the bones are certainly those of a mature adult.The following pathological changes were noted.     

Taphonomy of ungulate ribs and the consumption of meat and bone by 1.2-million-year-old hominins at Olduvai Gorge,Tanzania

The phenomenon of equifinality complicates behavioral interpretations of faunal assemblages from contexts in which Pleistocene hominins are suspected bone accumulators. Stone tool butchery marks on ungulate fossils are diagnostic of hominin activities, but debate continues over the higher-order implications of butchered bones for the foraging capabilities of hominins. Additionally, tooth marks imparted on bones by hominins overlap in morphology and dimensions with those created by some non-hominin carnivores, further confounding our view of early hominins as meat-eating hunters, scavengers or both. We report on the manual/oral peeling of cortical layers of ungulate ribs as taphonomically diagnostic of hominoid/hominin meat- and bone-eating behavior that indicates access to large herbivore carcasses by hominins at the site of BK, Olduvai. Supporting these inferences, we show that certain types of rib peeling damage are very rare or completely unknown in faunas created by modern carnivores and African porcupines, but common in faunas modified by the butchery and/or consumption activities of modern humans and chimpanzees, during which these hominoids often grasp ribs with their hands, and then used their teeth to peel strips of cortex from raggedly chewed ends of the ribs. Carnivores consume ungulate ribcage tissues soon after kills, so diagnostic traces of hominin butchery/consumption on ribs (i.e., peeling and butchery marks) indicate early access to ungulate carcasses by BK hominins. Tooth marks associated with the peeling and butchery marks are probably hominin-derived, and may indicate that it was not uncommon for our ancestors to use their teeth to strip meat from and to consume portions of ribs. Recognition of rib peeling as a diagnostic signature of hominoid/hominin behavior may also aid the search for pre-archaeological traces of hominin meat-eating.     

Foot amputation by the Moche of ancient Peru: osteological evidence and archaeological context

Three probable cases of foot amputation, with healing, in skeletal remains associated with the Moche culture (AD 100–750) of northern coastal Peru are described. Each case exhibits non‐functional tibio‐talar joints with proliferative bone occupying the normal joint space. The robusticity of the tibiae and fibulae suggest renewed weight‐bearing and mobility following recovery. The osteological evidence is consistent with details shown in Moche ceramic depictions of footless individuals. A footless Moche skeleton with wooden prostheses, described in 1913 by Peruvian physician Vélez López, appears to represent a fourth example of this procedure. The Moche surgical approach was similar to a technique that would be pioneered in western medicine by the Scottish surgeon Sir James Syme some 1500 years later.

Front and Back Covers,Volume 28, Number 2. April 2012

Front and back cover caption, volume 28 issue 2 Front cover A simple, austere cross hangs on the St. Maria‐Magdalena church in the newly constructed Rieselfeld neighbourhood of Freiburg im Breisgau, Germany. Completed in 2004, the building contains both a Protestant and a Catholic church, with moveable partition walls also allowing for the creation of a single ecumenical site when desired. Similarly, a diversity of associations, meanings, and histories are attributed to the symbol of the cross itself in different spaces and times. Its appearance on the wall of a multi‐ecumenical space highlights the theological connections between Protestant and Catholic Christianities; its location near the French‐German border calls attention to the doctrinal disputes and historical violence that have occurred between these two faiths. The significance of the cross – while often presumed to be self‐evident – is complex and ever shifting. Its connotations are produced through processes as diverse as the urban renewal project of the church of Maria‐Magdalena and juridical rulings on its display in public spaces. Recently, the European Court of Human Rights rejected a claim that crucifixes hanging in Italian classrooms were an affront to freedom of conscience and a parent's freedom to educate his or her children. As a symbol, the Court declared, the cross does not stand for Christianity alone, but also for ‘European heritage’. While today, signs associated with Islam are treated as a threat to public spaces in countries throughout Europe, anthropologists can explore how claims made about the cross produce it as a flexible sign connoting not only the story of the Passion, but also European history and secular tolerance. Back cover LEGENDARY HOMINOIDS Gregory Forth inspects what villagers in one part of western Flores describe as a burial mound marking the place where their ancestors interred a group of hominoids they killed in a violent confrontation. After receiving details of the mound and its history from Forth, in 2011 several Indonesian and Western palaeoanthropologists began exploring possibilities for excavating the site and hope to gain permission to begin digging in the near future. The 2003 discovery on the eastern Indonesian island of Flores of a small, physically primitive hominin interpreted as a new species, Homo floresiensis, came as a surprise to anthropology. Not only is the find extraordinarily recent in geological terms, but the hypothetical species bears a close resemblance to indigenous images of similarly diminutive, hominoid creatures reputedly encountered by local villagers in an even more recent historical era. The challenge posed by Homo floresiensis to our previous understanding of hominin (or ‘human’) evolution is well documented. But the unexpected find poses challenges for sociocultural anthropology as well. Searches for the physical remains of non‐sapiens hominins are typically motivated by prevailing palaeoanthropological theories and interpretations. However, contextual as well as physical peculiarities of the Flores hominin suggest that future investigations of the new species may be crucially informed by ethnographic evidence, the bulk of which was collected prior to, and independent of, the palaeoanthropological discovery.     

Vascular Grooves on Human Femora and Tibiae as a Potential Activity‐related Trait

The presence of vascular grooves on the shafts of femora and tibiae was scored for a sample of human remains from a mass burial at Tell Majnuna, Syria, dated to the early fourth millennium bce . In the sample of 140 femora and 64 tibiae, many of which were damaged or fragmented, the grooves were most common on the femoral midshaft (31/108 = 28.7%) and on the proximal and middle shaft of the tibia (10/45 = 22.2 and 14/54 = 26.0%, respectively). For femoral midshafts, the difference in mean cross‐sectional size and shape indices between bones with and without vascular grooves was checked with multivariate analysis of variance for a sample of 51 bones. The presence of grooves appeared to correspond significantly with higher mean values of both indices. As the shape index is interpreted as an indicator of the level of terrestrial mobility and the size index may be used for sex assessment, it is possible that vascular grooves occur more frequently at the femoral midshafts of men and more active individuals, and thus they may be cautiously interpreted as another activity‐related trait.

Comparison of 3D Landmark and 3D Dense Cloud Approaches to Hominin Mandible Morphometrics Using Structure‐From‐Motion

The objective of this study is to compare landmark‐based assessment of hominin mandible morphological variation with that from a high‐density point cloud, using 3D models constructed from structure‐from‐motion (SfM) surface capture techniques. Surface models of nine hominin mandible casts were created using SfM photogrammetry. The morphology of these models was described using traditional geometric morphometrics based on identification of landmarks. This was compared to the morphological variation described by the differences between high‐density point clouds, which do not rely on anatomical landmarks, using an iterative closest point algorithm. The landmark‐based approach grouped the anatomically modern human and Neanderthal mandibles with reasonable success. The high‐density point cloud approach also grouped these successfully, but was able to incorporate information from a specimen that was insufficiently preserved to be included in the landmark data set. This improved the accuracy of the grouping. The use of high‐density point clouds from surface capture to analyse hominin mandible morphology allows for greater amounts of information to be included and offers a potential method to identify shape affinity that is as successful as landmark‐based geometric morphometrics.     

Experimental study of cut marks made with rocks unmodified by human flaking and its bearing on claims of ∼3.4-million-year-old butchery evidence from Dikika, Ethiopia

In order to assess further the recent claims of ∼3.4 Ma butchery marks on two fossil bones from the site of Dikika (Ethiopia), we broadened the actualistic-interpretive zooarchaeological framework by conducting butchery experiments that utilized naïve butchers and rocks unmodified by human flaking to deflesh chicken and sheep long limb bones. It is claimed that the purported Dikika cut marks present their unexpectedly atypical morphologies because they were produced by early hominins utilizing just such rocks. The composition of the cut mark sample produced in our experiments is quite dissimilar to the sample of linear bone surface modifications preserved on the Dikika fossils. This finding substantiates and expands our earlier conclusion that—considering the morphologies and patterns of the Dikika bone surface modifications and the inferred coarse-grained depositional context of the fossils on which they occur—the Dikika bone damage was caused incidentally by the movement of the fossils on and/or within their depositional substrate(s), and not by early hominin butchery. Thus, contrary to initial claims, the Dikika evidence does not warrant a major shift in our understanding of early hominin behavioral evolution with regard to carcass foraging and meat-eating.     

Sex identification from the distal fibula

This study was designed to determine whether the fibula, which is one of the least studied long bones, can provide reliable information for sexing of human bones, provided that one condition is satisfied, namely, its distal end is available for measurement. The materials consisted of the dried fibulae of 71 Japanese males and 35 females whose names, ages and sex were known. The distal end of the fibula was measured with respect to five novel dimensions that are closely related to the soft tissues that had been attached to the bone surface. Highly significant sex differences were found when all parameters examined were considered together. The differences for separate items were not, however, sufficient for sex discrimination. Discriminant analysis was performed using the five parameters and yielded the correct sex with 90. 6 per cent accuracy for the entire group of specimens. This degree of accuracy suggests the utility of the present method for sexing human bones, in particular, in osteoarchaeological situations.     

Differential diagnosis of an unusual tibial pathology from Peru

During an osteological analysis of human skeletal remains from the site of Punta Lobos (Huarmey Valley, northern coastal Peru), an unusual erosive lesion of the cortex with periosteal reaction was observed on a right tibia. The authors undertook a review of paleopathological and medical literature to arrive at a differential diagnosis. The lesion is determined to be a non‐malignant growth, possibly a large periosteal ganglion, though a diagnosis of periosteal chondroma (a benign neoplasm) or other uncommon neoplasm could not be definitively ruled out.

Foot anomalies in the Late Neolithic/Chalcolithic population exhumed from the rock cut cave of São Paulo 2 (Almada,Portugal)

The study of developmental abnormalities of the tarsal bones in a Portuguese Late Neolithic population was performed, as part of an ongoing research project that includes the evaluation of foot defects in Portuguese skeletal populations from Neolithic times to modern 20th century samples. Two accessory bones were found, calcaneum secundarium and os trigonum, and three non‐osseous coalitions were detected, calcaneonavicular, cuboid‐navicular and third metatarsal‐third cuneiform. The newly presented frequencies corresponded to other published sources, except for the frequency of calcaneum secundarium, higher than in previous studies (8.6% left bones; 15.2% right bones). This result suggests population homogeneity maybe due to geographic isolation and/or marriage customs although the exact pattern of inheritance of the majority of these foot anomalies is unknown. No apparent sex bias was detected and side could not be tested since these human remains were uncovered from a commingled funerary context. Copyright © 2010 John Wiley & Sons, Ltd.     

Multiple bone tuberculosis in a child from predynastic Upper Egypt (3200 BC)

Tuberculosis, one of the most ancient human diseases, was present in ancient Egypt and has been observed since predynastic times. Excavations in the predynastic to early dynastic necropolis of Adaima, Upper Egypt (3500–2700 BC) led to the discovery of a number of remarkably well‐preserved skeletons of children. The skeletal remains of a 4.5–5‐year‐old child dated from Nagada III A2 (3200–3100 BC) displayed various lesions on the post‐cranial skeleton: spondylitis on the thoracic (T12) and lumbar (L1) vertebrae, partial lytic destruction of the right radio‐ulnar joint, lytic lesions on the scapula and a clavicle, dactylitis on the short bones of hands and feet, enlargement (spina ventosa) and periosteal new bone formation on the long bones. Radiographs show well‐defined radiolucent (cyst‐like) lesions in the metaphysis and the diaphysis of long tubular bones (ulna, radius, femur, tibia, fibula). The lesions recorded during macroscopic and radiological analysis strongly suggest a case of multiple bone tuberculosis. The occurrence of this case of tuberculosis in a child provides a picture of a period where tuberculosis must have been endemic throughout the population living during the origins of urban settlement in Upper Egypt during the predynastic period.

Taphonomy,life history,and human exploitation of Rhinoceros sinensis at the Middle Pleistocene site of Panxian Dadong,Guizhou, China

Rhinoceros remains are commonly found in Chinese Pleistocene archaeological localities. This study examines the characteristics of the Rhinoceros sinensis sample from Panxian Dadong, a karst cave in the mountains of western Guizhou province, with a mammalian fauna in association with stone artefacts and human remains from the late Middle Pleistocene (MIS 6‐8). The distribution of skeletal elements shows a predominance of foot (metapodial and phalanges) and lower limb (carpals and tarsals) bones, while the dental age‐at‐death profile, constructed using dental eruption and tooth wear data, is characterised by a high frequency of prime age adult teeth. There is little taphonomic evidence for the involvement of non‐human carnivores or natural agencies in the formation of the faunal assemblage. Instead, it appears that human activities were responsible for the unexpected prevalence of prime age adults. Copyright © 2008 John Wiley & Sons, Ltd.     

Skeletal Manifestations of Skin Ulcer in the Lower Leg

Skin ulcers of the lower leg are known to cause both destructive and, more commonly, bone‐forming lesions. Typically, bone‐forming lesions in this disorder have clearly defined margins although there may be extensive reactive bone formation involving much or all of the adjacent diaphysis. These lesions are best described in patients from tropical areas, and in these environmental contexts, these are known as tropical ulcers, but leg ulcers can be caused by a variety of diseases and conditions, of which vascular insufficiency plays an important role among the elderly. The lesions are important clinically because of the disability associated with the ulcer and because of complications that can develop including osteomyelitis and cancer. In most cases, the bone lesions caused by ulcer are easily diagnosed in archaeological human skeletal remains and provide some insight into the prevalence of this disorder in antiquity. In this paper, we review the gross and radiological manifestations of bone lesions resulting from overlying skin ulcer in tibiae of 13 cases including archaeological and modern medically documented skeletons. In two of the cases, there is medical documentation regarding the presence of a chronic ulcer on the lower leg. The objectives of this paper were to explore the diversity of bone lesions associated with ulcers of the tibia and to provide an improved basis for the diagnosis of this disorder in human skeletal remains.

Fractures of the lower limbs and their secondary skeletal adaptations: a 20th century example of pre‐modern healing

This study focuses on an old male skeleton, which shows severe fractures of the right femur and of the left tibia and fibula. The skeleton, complete and in a good condition of preservation, comes from a Sardinian osteological collection (from the beginning of 1900 AD) with known age, sex and life‐activity. The features of the fractures and pattern of joint disease, enthesis development and enthesopathies have been studied in order to ascertain a possible cause for these traumatic events, the functional implications for postural and locomotory behavior and, finally, the eventual evidence of medical treatment.
